Performance Monitoring
Performance monitoring (PM) parameters are used by service providers to gather, store, and set
thresholds, and to report performance data for early detection of problems. In this chapter, PM
parameters and concepts are defined for electrical cards, Ethernet cards, optical cards, and dense
wavelength division multiplexing (DWDM) cards in the Cisco ONS 15454.
Note
Release 4.7 is DWDM only. It supports all DWDM, transponder (TXP), and muxponder (MXP) cards
but not optical, electrical, storage media access, or Ethernet cards. DWDM cards include the OSCM,
OSC-CSM,OPT-PRE,OPT-BST, 32MUX-O, 32DMX-O, 32DMX, 4MD-xx.xAD-4B-xx.x, AD-1B-xx.x,
AD-4C-xx.x, AD-2C-xx.x, AD-1C-xx.x, and the 32WSS

4.1 Threshold Performance Monitoring
4.1 Threshold Performance Monitoring
Thresholds are used to set error levels for each PM parameter. You can set individual PM threshold
values from the Cisco Transport Controller (CTC) card view Provisioning tab. For procedures on
provisioning card thresholds, such as line, path, and SONET thresholds, refer to the Cisco ONS 15454
DWDM Installation and Operations Guide.
During the accumulation cycle, if the current value of a performance monitoring parameter reaches or
exceeds its corresponding threshold value, a threshold crossing alert (TCA) is generated by the node and
displayed by CTC. TCAs provide early detection of performance degradation. When a threshold is
crossed, the node continues to count the errors during a given accumulation period. If zero is entered as
the threshold value, generation of TCAs is disabled but performance monitoring continues.
Change the threshold if the default value does not satisfy your error monitoring needs. For example,
customers with a critical DS-1 installed for 911 calls must guarantee the best quality of service on the
line; therefore, they lower all thresholds so that the slightest error raises a TCA.
4.2 Intermediate Path Performance Monitoring
Intermediate path performance monitoring (IPPM) allows transparent monitoring of a constituent
channel of an incoming transmission signal by a node that does not terminate that channel. Many large
networks only use line terminating equipment (LTE), not path terminating equipment (PTE). Table 4-1
shows ONS 15454 cards that are considered LTE.

ONS 15454 Software R3.0 and higher allows LTE cards to monitor near-end PM data on individual STS
payloads by enabling IPPM. After enabling IPPM provisioning on the line card, service providers can
monitor large amounts of STS traffic through intermediate nodes, thus making troubleshooting and
maintenance activities more efficient.

Performance Monitoring
4.3 Pointer Justification Count Performance Monitoring
IPPM occurs only on STS paths that have IPPM enabled, and TCAs are raised only for PM parameters
on the IPPM enabled paths. The monitored IPPM parameters are STS CV-P, STS ES-P, STS SES-P,
STS UAS-P, and STS FC-P.
Note
Far-end IPPM is not supported by all OC-N cards. It is supported by OC3-4 and EC-1 cards. However,
SONET path PMs can be monitored by logging into the far-end node directly.
The ONS 15454 performs IPPM by examining the overhead in the monitored path and by reading all of
the near-end path PM values in the incoming direction of transmission. The IPPM process allows the
path signal to pass bidirectionally through the node completely unaltered.
For detailed information about specific IPPM parameters, locate the card name in the following sections
and review the appropriate definition.
4.3 Pointer Justification Count Performance Monitoring
Pointers are used to compensate for frequency and phase variations. Pointer justification counts indicate
timing errors on SONET networks. When a network is out of sync, jitter and wander occur on the
transported signal. Excessive wander can cause terminating equipment to slip.
Slips cause different effects in service. Voice service has intermittent audible clicks. Compressed voice
technology has short transmission errors or dropped calls. Fax machines lose scanned lines or experience
dropped calls. Digital video transmission has distorted pictures or frozen frames. Encryption service
loses the encryption key causing data to be transmitted again.
Pointers provide a way to align the phase variations in STS and VT payloads. The STS payload pointer is
located in the H1 and H2 bytes of the line overhead. Clocking differences are measured by the offset in
bytes from the pointer to the first byte of the STS synchronous payload envelope (SPE) called the J1
byte. Clocking differences that exceed the normal range of 0 to 782 can cause data loss.
There are positive (PPJC) and negative (NPJC) pointer justification count parameters. PPJC is a count
of path-detected (PPJC-PDet-P) or path-generated (PPJC-PGen-P) positive pointer justifications. NPJC
is a count of path-detected (NPJC-PDet-P) or path-generated (NPJC-PGen-P) negative pointer
justifications depending on the specific PM name. PJCDIFF is the absolute value of the difference
between the total number of detected pointer justification counts and the total number of generated
pointer justification counts. PJCS-PDet-P is a count of the one-second intervals containing one or more
PPJC-PDet or NPJC-PDet. PJCS-PGen-P is a count of the one-second intervals containing one or more
PPJC-PGen or NPJC-PGen.
A consistent pointer justification count indicates clock synchronization problems between nodes. A
difference between the counts means the node transmitting the original pointer justification has timing
variations with the node detecting and transmitting this count. Positive pointer adjustments occur when
the frame rate of the SPE is too slow in relation to the rate of the STS 1.
You must enable PPJC and NPJC performance monitoring parameters for LTE cards. See Table 4-1 on
page 4-2 for a list of Cisco ONS 15454 LTE cards. In CTC, the count fields for PPJC and NPJC PMs
appear white and blank unless they are enabled on the card view Provisioning tab.
For detailed information about specific pointer justification count PM parameters, locate the card name
in the following sections and review the appropriate definition.

Facility Data Link (FDL) performance monitoring enables an ONS 15454 DS1N-14 card to calculate and
report DS-1 error rate performance measured at both the near-end and far-end of the FDL. The far-end
information is reported as received on the FDL in a performance report message (PRM) from an
intelligent channel service unit (CSU).
To monitor DS-1 FDL PM values, the DS-1 must be set to use Extended Superframe (ESF) format and
the FDL must be connected to an intelligent CSU. For procedures on provisioning ESF on the DS1N-14
card, refer to the Cisco ONS 15454 Procedure Guide.
The monitored DS-1 FDL PM parameters are CV-PFE, ES-PFE, ESA-PFE, ESB-PFE, SES-PFE,
SEFS-PFE, CSS-PFE, UAS-PFE, FC-PFE, and ES-LFE. For detailed information about specific DS-1
FDL PM parameters, locate the DS1N-14 card name in the following sections and review the appropriate
definition.
4.6 Performance Monitoring for Electrical Cards
The following sections define performance monitoring parameters for the EC1-12, DS1-14, DS1N-14,
DS3-12, DS3-12E, DS3N-12, DS3N-12E, DS3XM-6, DS3XM-12, and DS3/EC1-48 cards.
4.6.1 EC1-12 Card Performance Monitoring Parameters
Figure 4-1 shows signal types that support near-end and far-end PMs. Figure 4-2 shows where overhead
bytes detected on the application specific integrated circuits (ASICs) produce performance monitoring
parameters for the EC1-12 card.

4.7 Performance Monitoring for Ethernet Cards
The following sections define performance monitoring parameters and definitions for the ONS 15454
E-Series, G-Series, and ML-Series Ethernet cards.
4.7.1 E-Series Ethernet Card Performance Monitoring Parameters
CTC provides Ethernet performance information, including line-level parameters, port bandwidth
consumption, and historical Ethernet statistics. The E-Series Ethernet performance information is
divided into the Statistics, Utilization, and History tabbed windows within the card view Performance
tab window.
4.7.2 E-Series Ethernet Statistics Window
The Ethernet statistics window lists Ethernet parameters at the line level. The Statistics window provides
buttons to change the statistical values shown. The Baseline button resets the displayed statistics values
to zero. The Refresh button manually refreshes statistics. Auto-Refresh sets a time interval at which
automatic refresh occurs.
Table 4-11 defines the E-Series Ethernet card Statistics parameters.
Table 4-11 E-Series Ethernet Statistics Parameters
Parameter
Definition
Link Status
Indicates whether link integrity is present; up means present, and down
means not present.
Rx Packets
Number of packets received since the last counter reset.
Rx Bytes
Number of bytes received since the last counter reset.
Tx Packets
Number of packets transmitted since the last counter reset.
Tx Bytes
Number of bytes transmitted since the last counter reset.
Rx Total Errors
Total number of receive errors.
Rx FCS
Number of packets received with a Frame Check Sequence (FCS) error.
FCS errors indicate frame corruption during transmission.
Rx Alignment
Number of packets with alignment errors. Alignment errors are received
incomplete frames.
Rx Runts
Number of undersized packets received with bad cyclic redundancy check
(CRC) errors.
Rx Shorts
Number of undersized received packets with good CRC errors.
Rx Oversized + Jabbers
Measures oversized packets and jabbers. Size is greater than 1522 errors
regardless of CRC errors.
Tx Collisions
Number of transmit packets that are collisions; the port and the attached
device transmitting at the same time caused collisions.
Tx Late Collisions
Number of frames that were not transmitted since they encountered a
collision outside of the normal collision window (late collision events
should occur only rarely).

Parameter
Definition
Tx Excessive Collisions
Number of consecutive collisions.
Tx Deferred
Number of packets deferred.
4.7.3 E-Series Ethernet Utilization Window
The Utilization window shows the percentage of transmit (Tx) and receive (Rx) line bandwidth used by
the Ethernet ports during consecutive time segments. The Mode field displays the real-time mode status,
such as 100 Full, which is the mode setting configured on the E-Series port. However, if the E-Series
port is set to autonegotiate the mode (Auto), this field shows the result of the link negotiation between
the E-Series and the peer Ethernet device attached directly to the E-Series port.
The Utilization window provides an Interval menu that enables you to set time intervals of 1 minute,
15 minutes, 1 hour, and 1 day. Line utilization is calculated with the following formulas:
Rx = (inOctets + inPkts * 20) * 8 / 100% interval * maxBaseRate
Tx = (outOctets + outPkts * 20) * 8 / 100% interval * maxBaseRate
The interval is defined in seconds. The maxBaseRate is defined by raw bits per second in one direction
for the Ethernet port (that is, 1 Gbps). The maxBaseRate for E-Series Ethernet cards is shown in
Table 4-12.

Note
Line utilization numbers express the average of ingress and egress traffic as a percentage of capacity.
Note
The E-Series Ethernet card is a Layer 2 device or switch and supports Trunk Utilization statistics. The
Trunk Utilization statistics are similar to the Line Utilization statistics, but shows the percentage of
circuit bandwidth used rather than the percentage of line bandwidth used. The Trunk Utilization statistics
are accessed via the card view Maintenance tab.
4.7.4 E-Series Ethernet History Window
The Ethernet History window lists past Ethernet statistics for the previous time intervals. Depending on
the selected time interval, the History window displays the statistics for each port for the number of
previous time intervals as shown in Table 4-13. The listed parameters are defined in Table 4-11 on
page 4-25.

4.7.5 G-Series Ethernet Card Performance Monitoring Parameters
CTC provides Ethernet performance information, including line-level parameters, port bandwidth
consumption, and historical Ethernet statistics. The G-Series Ethernet performance information is
divided into the Statistics, Utilization, and History tabbed windows within the card view Performance
tab window.
4.7.6 G-Series Ethernet Statistics Window
The Ethernet statistics window lists Ethernet parameters at the line level. The Statistics window provides
buttons to change the statistical values shown. The Baseline button resets the displayed statistics values
to zero. The Refresh button manually refreshes statistics. Auto-Refresh sets a time interval at which
automatic refresh occurs. The G-Series Statistics window also has a Clear button. The Clear button sets
the values on the card to zero, but does not reset the G-Series card.

Number of transmit queue drops due to drops in the G-Series
frame buffer.
HDLC Errors
High-level data link control (HDLC) errors received from
SONET/SDH (see Note).
Rx Unicast Packets
Number of unicast packets received since the last counter
reset.
Tx Unicast Packets
Number of unicast packets transmitted.
Rx Multicast Packets
Number of multicast packets received since the last counter
reset.
Tx Multicast Packets
Number of multicast packets transmitted.
Rx Broadcast Packets
Number of broadcast packets received since the last counter
reset.
Tx Broadcast Packets
Number or broadcast packets transmitted.
Do not use the high level data link control (HDLC) errors counter to count the number of frames dropped
because of HDLC errors, because each frame can fragment into several smaller frames during HDLC
error conditions and spurious HDLC frames can be generated. If HDLC error counters are incrementing
when no SONET path problems should be present, it might indicate a problem with the quality of the
SONET path. For example, a SONET protection switch generates a set of HDLC errors. However, the
actual values of these counters are less significant than the fact that they are changing.
4.7.7 G-Series Ethernet Utilization Window
The Utilization window shows the percentage of Tx and Rx line bandwidth used by the Ethernet ports
during consecutive time segments. The Mode field displays the real-time mode status, such as 100 Full,
which is the mode setting configured on the G-Series port. However, if the G-Series port is set to
autonegotiate the mode (Auto), this field shows the result of the link negotiation between the G-Series
and the peer Ethernet device attached directly to the G-Series port.
The Utilization window provides an Interval menu that enables you to set time intervals of 1 minute,
15 minutes, 1 hour, and 1 day. Line utilization is calculated with the following formulas:
Rx = (inOctets + inPkts * 20) * 8 / 100% interval * maxBaseRate
Tx = (outOctets + outPkts * 20) * 8 / 100% interval * maxBaseRate

Unlike the E-Series cards, the G-Series cards do not have a display of Trunk Utilization statistics because
the G-Series card is not a Layer 2 device or switch.
4.7.8 G-Series Ethernet History Window
The Ethernet History window lists past Ethernet statistics for the previous time intervals. Depending on
the selected time interval, the History window displays the statistics for each port for the number of
previous time intervals as shown in Table 4-16. The listed parameters are defined in Table 4-14 on

the values on the card to zero, but does not reset the CE-100T-8 card.
During each automatic cycle, whether auto-refreshed or manually refreshed (using the Refresh button),
statistics are added cumulatively and are not immediately adjusted to equal total received packets until
testing ends. To see the final PM count totals, allow a few moments for the PM window statistics to finish
testing and update fully. PM counts are also listed in the CE-100T-8 card Performance > History window.

4.9.2 MXP_MR_2.5G/MXPP_MR_2.5G Utilization Window
The Utilization window shows the percentage of Tx and Rx line bandwidth used by the ports during
consecutive time segments.
The Utilization window provides an Interval menu that enables you to set time intervals of 1 minute,
15 minutes, 1 hour, and 1 day. Line utilization is calculated with the following formulas:
Rx = (inOctets + inPkts * 20) * 8 / 100% interval * maxBaseRate
Tx = (outOctets + outPkts * 20) * 8 / 100% interval * maxBaseRate
The interval is defined in seconds. The maxBaseRate is defined by raw bits per second in one direction
for the port (that is, 1 Gbps). The maxBaseRate for MXP_MR_2.5G/MXPP_MR_2.5G cards is shown
in Table 4-28.

4.10 Performance Monitoring for Storage Media Access Cards
The following sections define performance monitoring parameters and definitions for storage media
card, also known as the FC-MR-4 or Fibre Channel card.
CTC provides FC_MR-4 performance information, including line-level parameters, port bandwidth
consumption, and historical statistics. The FC_MR-4 card performance information is divided into the
Statistics, Utilization, and History tabbed windows within the card view Performance tab window.
4.10.1 FC_MR-4 Statistics Window
The Statistics window lists parameters at the line level. The Statistics window provides buttons to change
the statistical values shown. The Baseline button resets the displayed statistics values to zero. The
Refresh button manually refreshes statistics. Auto-Refresh sets a time interval at which automatic

4.10.2 FC_MR-4 Utilization Window
The Utilization window shows the percentage of Tx and Rx line bandwidth used by the ports during
consecutive time segments. The Utilization window provides an Interval menu that enables you to set
time intervals of 1 minute, 15 minutes, 1 hour, and 1 day. Line utilization is calculated with the following
formulas:
Rx = (inOctets + inPkts * 24) * 8 / 100% interval * maxBaseRate
Tx = (outOctets + outPkts * 24) * 8 / 100% interval * maxBaseRate
The interval is defined in seconds. The maxBaseRate is defined by raw bits per second in one direction
for the port (that is, 1 Gbps or 2 Gbps). The maxBaseRate for FC_MR-4 cards is shown in Table 4-31.
